BOTTLE STOPPER.

SPECIFICATION forming part of Letters Patent No. 365,961, dated July 5, 1887.

Application filed April 4, 1887.

T0 aZZ whom it may concern:

Be it known that 1, WILLIAM BEARDSLEY, of Beacon, in the county of Mahaska and State of Iowa, have invented a new and Improved Bottle-Stopper, of which the following is a full, clear, and exact description.

This invention relates to an improvement upon that class of bottlestoppers of which an example is given in Letters Patent No. 317 ,7 O5, granted to me on the 12th day of May, 1885, the object of the present invention being to dispense with the retaining-cap shown in the Letters Patent above referred to, and at the same time to provide a stopper which shall be so constructed and arranged as to be selfadjusting, and one which, after the bottle has once been closed, will not be liable to become accidentally displaced so as to open the bottle.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar figures of reference indicate corresponding parts in both the views.

Figure 1 is a view in central vertical section of a bottle provided with my improved form of stopper, the parts being represented as they appear when the bottle is open and empty; and Fig. 2 is a similar view represent ing the bottle, however, as it appears when filled and the stopper as in place against its packing'ring.

In constructing such a stopper as the one illustrated in the drawings above referred to, I provide a bottle, 10, in the head of which there is formed an annular recess, 11, the lower portion of said recess being of greater diameter than the upper portion thereof, so that the annular defining-walls of the recess are inclined, as shown at 2. \Vithin the recess 11, I fit a ring, 12, that is made of flexible packing material, and preferably of rubher, the walls defining the bore of the ring and the outer peripheral face of said ring being vertical or parallel to the axis of the bottle. Prior to the introduction of the ring I pass a stopper, 14, within the bottle 10, said stopper being spherical and of any proper material, such as porcelain, cork, or metal. An inspection of Fig. 1 will show that when the stopping-ball 14 is not in contact with the Serial No. 233,596.

ring 12 said ring does not entirely fill the groove 11, there being quite a space between the lower portion of the face of the ring and the inclined face 2 of the recess 11; but after the bottle has been filled (and it will of course be understood that the class of bottles to which this invention is applicable are designed for use as receptacles for aerated liquids) the pressure of the gas with which the contents of the bottle is charged will act to force the ball 14 upward within the bore of the packing-ring 12, which ring, when so subjected to pressure, will expand at its lower edge and entirely fill the groove ,11, the ball passing well up into the bore of the ring, as shown in Fig. 2, so that should the contents of the bottle be unduly cooled, andthe pressure thereby decreased, the ring itself will bind upon the stopper and act to hold it in position. It will be noticed from the construction illustrated in the drawings that the recess 11 is depressed at a point about in line with the greatest expansionof the bottle-head, so that, although the definingwalls of the recess are inclined, the glass is not thinner at the lower portion than at the upper portion of the groove or recess.

I am aware that a bottle has been formed with an internal annular groove having its peripheral definingwalls inclined outwardly and adapted to receive a packing having its peripheral face beveled or inclined to correspond with the defining-walls of the groove, and against the under surface of which a ball in the bottle rests when the bottle is filled, and I therefore do not claim such invention. I form the defining-walls of the bore of the ring and the outerperipheral face of the same vertical or parallel to the axis of the bottle, so that when placed in the groove it will not entirely fill the same, thereby permitting it to expand to receive the ball within its bore and hold the same therein, thus preventing all liability of the ball being accidentally displaced and the bottle unstoppcd.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 1 The combination, with a bottle provided with an annular internal groove having onting the packing-ring to expand to receive the Wardly-inolined vdefining-Walls, of an elastic ball withing its bore and hold. the same seapertured packing-ring having the definingcurely therein, as set forth.
